The shellof the kcartridge is denoted by a projectile 2 which is secured to the shell in any well known and approved manner.

Af longitudinally .arrangedA tube i is t screwed or otherwise secured to the end wall l of the shell 1i, the forward end, of which tube terminatesin the air chamber 5 andi has a plurality of 4lateral openings 6 in its sides, which chamber `5 and powder in the shell.

A fulminate 7 is held in the forward end of the tube?)` by means of a wad 8 of metal or other suitable material.

form passages into the air A` firing pin 91 is` inserted in the tube 3,;

with itsl outer end engaging the wad 8 and the innerend projecting a proper distanceu through the end wall 4t in position to be struck by the shown). This firing pin `9 is held in the tubey 3, against unintentional displacement by means of a spring-actuated tongue l0, c-utfrom the` pin, :whichtongue extends latj distance to engage a longitudinal slot 11 in the tube 3. When the pin is inserted inthe tube, the tongue 10 the walls of the tube until it reaches the slotV 11, where it will spring outwardly and thus lock the pinin,

the tube. The slot 11 is made long enough to allow the tongue to slide therein to the limitof the outward or firing movement of the pin. After the pin is struck b ing piece (not shown), and the lminate ignited, the flames therefrom will pass the projectile.

It has also been recognized that where all the powder in the charge is consumed, as in my improved cartridge, the usual erosion ofthe gun barrel is avoided.

While I have shown a cartridge of the in Vmagazine rifles, machine guns,

it will be understood that my device well adapted for use in other aving projectiles.
